GATE.

Application filed September 6, 192i. Serial No. 498,776.

To @ZZ/whom 'it may concern: one or the gate members and the brace: Be it known that l, DANIEL H. Davis, a and citizen of the United States, and a resident Figure 7 shows top view oli' the gate in 50 of Union, in the county of Hardin and State one of its adjusted positions. l of Iowa, have invented a certain new and My gate structures are designed to be useful Gate, of which the following is a used in connection with separate or indi specification. Yidual hog pens.

The object of niy invention is to provide ln the accompanying drawings, l have 55 a gate for hog lots and the like, which is used the reference numeral l0 to indicate a 10 so constructed and so arranged as to be opfence or the like. The fence l() is connected erated by the hogs themselves so thatthey at one end with a tence 'll extending for may be self-protecting. instance at right angles thereto and torm- More particularly, it is my object to proing one ot the walls of the fences of the pen. 60 vide such a gate structure, yhaving parts so It will be understood that if the wall l0 arranged that when the gate is set for the is the front wall and the Wall ll one ot the purpose, the passage of: one hog therethrough Side falls, then the pen has the back wall will operate to close the gate. and the other side wall or tence l2.

Still a further object is to provide such a A. fence i8 extends from the tence l2 par- 65 structure, which can be arranged at the allcl and spaced trom the tence l0 to a entrance to a pen and set so that the inner point spaced from the Jience ll as shown in passage of one hog will close the gate, and Figure l. lt will thus be seen that there is capable of being adjusted or set so as to a runway between the fences l() and l?) open allow the inward passage of any desired at one end and closed at the other end by 70 predetermined number of hogs. the fence il.

A further object is to make such a gate` rEhe tence i3 terminates at such a point with parts so arranged that hogs may leave spaced from the tence 1l as to permit tree the pen through the gate at any time withpassage troni the runway into the pen. eut being interfered with by the gate. lt will be understood that the tence 13 75 l/Vith these and other objects in view, my has the posts lli and the bor. is or other invention consists in the construction, arfence material l5 shown for instance in rangement and combination of the various Figure 3. parts of my device, whereby the objects con- Supported on the posts la is a filler block templated are attained, as hereinafter more l@ arranged at the tcp of said posts. Eii- 8O fully set forth, pointed out in my claims, tending laterally into the pen from the filler 3,5 and illustrated in the accompanying drawblock 16 and the posts lli is a board or inos, in which: y the like "i7, at the inner edge or which is 2Figure l shows a top or plan view of a an upwardly extending board or the like 1S. gate structure embodying my invention. lt will be seen that the filler block 16 S5 Figure 2 shows a detail, sectional view and board 18 torni the sides and that the taken on the line 2-2 of Figure l.' board l? forms the bottoni ot a guide or Figure 3 shows a detail, sectional view trough. ln the guide or trough thus iprined, taken on the line 3 3 ot' Figure 2. there is slidably mounted a bar 19 in which Figure l shows a detail, sectional view l provide a series of equi-distantly space 90 taken on the line 4.--41 of Figure l. transverse grooves 20. The grooves 2O are 45 Figure 5 shows a detail, perspective view in the Vupper surface of the bar 19, which l of a portion of the movable gate members. will call the slide bar. Near one edge of the Figure 6 is a detail view of a portion et slide bar 19 farthest from the fence 13, the

fence 13 nearest the fence 11, as shown in Figure 1. i

Secured'to the topy of vthe svyinging gate 22 are `pintles 23, which are `mounted in bearings 24k on the tops of the posts of the respective fences 13 and 10. llhe pintles 23 may be in the t'orin of rods. On the pintle 23, which is journaled on the fence 10, is `a crank handle 25. The pintle 23 at the opposite side of the gate 22 has an upwardly eX- tending arm 26. `Piv'oted tothe upwardly extending arm 26 are oppositely extending curved relatively 'long paivls 27 and 28,'the free ends of Which-,rest on the top of the slide bar 19 and are adapted to drop into the grooves 20.

it will thus be lseen that when the gate 22 is swung from its hanging vertical position upwardly in either direction, the arm 26 Will beinclined and one of the pawls 2T or 28, as the case may be, will-enter one ot'the .notches 20 and move the slide bar 19.

ln order to prevent the return movement oi the slide bar when the gate drops again to vertical position, l have provided on the iiller bar 13 a pair of projecting guide plates 29 and 30 below the pawls 27 and 23 near the tree ends thereof. Thus it will be seen by an inspection of Figure 3, that it the gate 22 swung upwardly toward'the left, the pawl 23 will engage one ot the notches 20 and slide'the bar 19 toward the right. The pawl 27 will then slide upon the guide plate 29, so that when the gate 22'sxvings downwardly, the paivl 27 will not return the bar 19' to its original position.

Spaced from the 22 toward the entrance end of the runway between the fences 10 and'13 is a double Laate me: ber. One of said gate members 31 is hinged by the inembers 32 and 33 and the pintle Pill tothe tence 13. The member 32 is secured to the gate member v31, kand the member 33 to the tence 13.

Between the members 32 and33 is a hinge member 353 mounted on the pintle 3i and secured to a `gatemeniber 36 similar in construction to the gate inembei31. There are two or more oi said hinge structures, vertically spaced.

The gate members 31 and 36 are Wider than the runway, so that'theycan not be s'wui'i'g to position transversely of the runway.y f

lln Figure 1, l have 4shown the gate 31 in full lines in open position and in dotted lines in closed position, Where it extends diagonally across the runway.

Fixed to the top of the gate member 31 near the hinged edge thereof is an arm 37 projecting in both directions from the gate member 31 and inclined from a right angle with relation to the gate 31, as shown in Figure 1. 37, which projects over Vthe slide bar is a coil spring 38 which is also secured to one of the posts of the tence 10. rillhe arm 37 is so arranged that when the gate 31 is in open position, as shown in Figure l, the arm has been moved past center and the spring 3S will tend to hold the gate in open position, 'Whereaswhen the gate 31 is moved to closed i position, as shown by dotted lines in Figure 1- the arm 37 will swing over center and the spring 33 Will tend to hold the gate 31 in such closed position.

Secured tothe upper part of the gate 31, as shown in igure 1, is a brace 39 inclined away from the gate 31 andA toward the hinged end thereof and projecting substantiallv beyond the hinged `end thereof. as illustra l The end oi the arm 37, which projects above the runway is secured/to said brace 39.

`tlem'nfed to the free end'of the brace 39 is a foil spring 19, which may be hooked over a pin i1 on the gate member 36 for yieldingly connecting` the gate members 31 and 36 and holding them in such position that they 'form a Wide-mouthed V.

Mounted in the gate member 36 for rotation a short rod i-2 having a head 13 arranged at right angles to thegbody of the rod. ln the bracel in the end. thereof farthest 'from the gate 31 is a slot 44. illustrated in Figure 6, through which the rod 12 projects when the gates 31 and 33 are connected together. The rod 4t2 may berotated :tor causing the head a3 to engage the brace 39 for locking the tvro gate members together. i

Underneath the filler bloeit a flat vspring i5 is provided for bearing against the side 0;'. the slide bar 1,9 for holouw ing it snugly against `the guide -Wall or board 18. The filler blocklt is broken away in Figure 1 to show such operation. u

lilonted on the tence 10 is a sra/*inging hooi; member e3, .vhich. when gate 22 is 'fully raised, maybe swung toposition for holdingit in raised position, by projecting the :tree i or strip 16.

end oil the hook 116 into a hole in the edge ot the gate 22 or beneath the .q'ate e2.k

Secured to the end of the armk ifi/laas? en tion of my improved gate structure and such explanation will. make more clear the construction and arrangement ot the parts.

Assuming that it is desired to use several oi the pens equipped with my gate structure in a hog lot, in which there are a number of brood sows, and assume that it is desirable to arrange the gate structure so that one sowronly can enter a pen and upon her entrance will shut the gates, so that she may be alone in the pen, it she desires.

ln such case, the gate 22, is raised and held in raised position by the hook member 46. The gate members 31 and 36 are connected together by means ot the spring 40 and the pin a1, and the gate 31 is lett in its open position as shown in Figure 1, and it will be seen that the gate 36 will then be in its closed position.

lt one hog desires to enter the pen, it may walk in through the runway pushing against the gate 36 and opening it and thereby swinging the gate 31 toward closed position until the arm 87 swings past center whereupon the spring 38 will hold the gate $551 in closed position. Owing to the yielding connection ol the gate members 31 and 36, 'the gates will not bind on the hog. rlhe hog may then enter the pen and will be iree from interference or excitement. No other hog can enter the pen, however, the hog, which is in the pen may readily leave the pen by walking out through the runway and pushing the gate 81 to open position, whieifh will move the gate 36 to closed po sition, as the arm 37 swings over center.

Assuming, however, that it is desired to arrange the gate so that six hogs may enter the pen, the rod 42 is rotated Vtor releasing the brace 39 and the spring 40 is released.v

The gate 36 is then secured against the tence 13 hy means ot the hook 47 and pin L18. The

` gate 31 is swung to `open position and will le held there by the spring 38. rlhe gate 2 is released and lowered. The pin i9 is et in the proper hole 2 1 and the slide bar 9 is then moved to such position that live inward swings of the gate 22 will cause the pawl 28 to live times advance the slide bar 19. 'lhe pin 49 is so set that on the sixth sliding movement ot the bar 19, said pin will engage the arm 37 and swing it past center l'or closing the gate 31, thus limiting the number or hogs that can enter the pen. lt will be noted that after any certain number of hogs, less than seven, has entered the pen, Jfor instance six, any one of the hogs may freely leave the pen to go out to the water trough or otherwise. Upon leaving` the pen, the gate 22 will be swung and will cause the pawl 27 to move the bar 19 one notch toward the lett, thus leaving the bar 19 in such position that one more hog may enter the pen and join the five already therein. i

rl`he hogs :finding that they can i leave the pen will have no hesitancy aber entering it.

l/Vhen the gates are arranged in the lirst of the positions above-mentioned, towith the gates ill and 36 connected, the soon learn that upon entering the pen they tree trom interference by other animals, and they lireely enter and leave the pen.

The advantage ot having such a structure is very obvious. i 7owl sow can enter the pen when she desires and close the gate and the stocln'aisei` is freed 'trom the necessity ot being constantly on the watch.

The advantages of such a gate structure as has been described will l e largely obvious from the foregoing; description.

Attention may Le called to the fact, however,V that it is highly desirable in car' for brooding sows belfort it-rrowing t` sows should be able to go into one of the pens and he tree trom annoyance and interterence.

lt will seen that by properly setting the gate, one sow may go into the pen and she will shut the ate, so that she may remain in the pen t Vlout interference on the part ot the other hogs. However, she i'reely wall; out oi the pen and when she does so, will open the gate, so that the saine sow or another sow may afterward go into the pen and close the gate. l

lt well-linown that in raisimg` hogs particularly on cold nights, the hoo will bunch up and pile up and 'frequently some ot the hogs are nmothered under the aile.

:.Hith the incre vlue or" hogs and particularly ot bloo L stock, this imposes on the farmers severe losses, which can be avoided by the use of my gate.

lt will be that b" adjustin.` the slide bar,`the s. L the entrance of any into any particular pen. 'lhus each gate can be seen so set that only a certain number olV L i. The mer, will, Aor different numbers j upon the sine and condie tion of the h the large lot, and will set the gate so that only such number ot hooge can enter any one pen, so that the hogs in the pen will be sa'l'e from heing smothered in the pile.

Attention is alled to the lac-t that the gate is automatic, so that it requires comparatively little attention. on the parl of course, set ot hogs depe structure or use oi mechanical equivalents,

which may ybe reasonably included within the scope of my claims.
